SP207EEA-L RS232 Transceiver Equivalent & Substitute Parts

Part Overview

The SP207EEA-L is a full-duplex RS232 transceiver manufactured by MaxLinear, Inc., featuring 5 drivers and 3 receivers in a 24-SSOP surface mount package. This part is discontinued at DiGi Electronics. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for production and repair applications. Suitable alternatives must maintain compatibility across electrical specifications, package dimensions, and protocol requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the SP207EEA-L is determined by the following critical parameters:

Protocol: RS232 (all substitutes must support RS232)
Configuration: 5 drivers / 3 receivers (full-duplex transceiver)
Package: 24-SSOP with 5.30mm width (physical and electrical pin compatibility)
Supply Voltage: 4.5V – 5.5V operating range (or compatible subset)
Data Rate: Minimum 230 kbps (SP207EEA-L specification)

Substitute parts are grouped by manufacturer and packaging format. All listed substitutes maintain the 24-SSOP package footprint and RS232 protocol compliance. Variations in receiver hysteresis, operating temperature range, and moisture sensitivity level do not preclude substitution when other parameters align.

Engineering Selection Recommendations

For direct replacement of the discontinued SP207EEA-L, the ADM207EARSZ and ADM207EARSZ-REEL are the primary candidates. Both are manufactured by Analog Devices Inc., maintain active product status, and support the full 230 kbps data rate specification. These parts are available in tube and tape & reel packaging formats respectively, with ROHS3 compliance and superior moisture sensitivity ratings (MSL 1, Unlimited).

The ICL3207ECAZ and ICL3207ECAZ-T from Renesas Electronics Corporation offer the highest data rate capability at 250 kbps and extended supply voltage range (3V – 5.5V). However, the operating temperature range is narrower (0°C – 70°C versus -40°C – 85°C), which may limit suitability for extended industrial temperature applications.

The MAX207 series variants (MAX207CAG+, MAX207CDBR, MAX207ECAG+) are limited to 120 kbps data rate and narrower supply voltage windows (4.75V – 5.25V). MAX207CDB is obsolete and should not be selected for new designs. These parts are suitable only when application data rates do not exceed 120 kbps.

All substitute parts maintain the 24-SSOP package footprint and full-duplex 5/3 driver/receiver configuration. Selection should prioritize active product status and compliance certifications for production continuity.

Frequently Asked Questions (FAQ)

Q: Can ADM207ARSZ replace SP207EEA-L directly?

A: ADM207ARSZ is electrically compatible in terms of package, protocol, and driver/receiver configuration. However, it operates at 120 kbps maximum data rate, compared to SP207EEA-L's 230 kbps specification. Use this part only if your application data rate does not exceed 120 kbps.

Q: What is the difference between ADM207EARSZ and ADM207EARSZ-REEL?

A: Both parts are identical in electrical specifications and support 230 kbps data rate. The difference is packaging format: ADM207EARSZ is supplied in tube packaging, while ADM207EARSZ-REEL is supplied in tape & reel format for automated assembly. Select based on your procurement and assembly requirements.

Q: Is ICL3207ECAZ suitable for -40°C to 85°C applications?

A: No. ICL3207ECAZ operates from 0°C to 70°C. For applications requiring -40°C to 85°C operation, use ADM207EARSZ or ADM207EARSZ-REEL, which maintain the full temperature range of the original SP207EEA-L.

Q: Why do MAX207 variants have a narrower supply voltage range?

A: MAX207 series parts specify 4.75V – 5.25V supply voltage, which is a subset of the 4.5V – 5.5V range supported by SP207EEA-L and ADM207 variants. Verify your power supply tolerance before selecting MAX207 parts.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, meeting current environmental and hazardous substance restrictions.

Q: Can I use MAX207CDB in new production?

A: No. MAX207CDB is marked as obsolete and should not be selected for new designs. Use MAX207CDBR (active status) or ADM207EARSZ series for production applications.

Q: What does MSL rating mean for component selection?

A: Moisture Sensitivity Level (MSL) indicates the component's sensitivity to moisture during storage and handling. SP207EEA-L has MSL 2 (1 Year), while ADM207 variants have MSL 1 (Unlimited), providing superior shelf life and reduced risk of moisture-induced failures during assembly.
